Abstract (en)
An anti-theft system is arranged so that an operation of an engine of a vehicle is maintained as it is even when a CPU (32a) of an engine control unit (30, 30A) is reset for some reason during when the engine is operative. A CPU (21a) of a security ECU (20) performs arithmetic operations for enabling or inhibiting injection of fuel to the engine and for enabling to start a starter (40) on condition that a door key switch (10a) and an ignition switch (10b) are both turned on. The CPU (32a) of the engine ECU (30) performs arithmetic operations to maintain the injection of fuel to the engine based on data of fuel injection enabling or inhibiting process stored in a B/U RAM (34) even when it is reset after receiving the data of process for enabling or inhibiting the injection of fuel from the CPU (21a). <IMAGE>
